UD Western Sierra Puebla Nahuatl-IU is a treebank consisting of sentences from written fiction and non-fiction, spontaenous speech, and grammar examples.

The treebank was pre-annotated for morphology using the apertium-nhi (Pugh et al, 2021). The morphological analyses were disambiguated and annotated for dependency structure by hand.
